please answer all parts 4. Least Square Method A. (10 points) Use the least squares method and find a linear fit for the following points: (0, -3), (2, -3), (1, -4), (4,5) B. Short Answer: (5 points) Quickly plot the points (by hand) and comment on the likely quality of the linear fit. Would another type of curve fit be better suited?
